Piell participated in the Battle of Geonosis, which marked the beginning of the Clone Wars.[7] During the later years of the Clone Wars, the aged Jedi was tasked with investigating shortcuts into Separatist-held space. Master Piell discovered the Nexus Route, a hyperlane route that allowed one to access both Separatist and Republichomeworlds. The Nexus route held strategic importance to both the Confederacy of Independent Systems and the Galactic Republic, to the extent that while returning from an assignment, Jedi Master Even Piell's ship was waylaid by Separatists. Piell and his crew (including CaptainWilhuff Tarkin) were eventually captured and imprisoned at the Citadel.[8] In the course of escaping the detention facility, after being freed by a Jedi and clone trooper strike team,[9] Even Piell was gored by a vicious Anooba and, subsequently, expired from his wounds--after having revealed his part of the co-ordinates of the Nexus Route to PadawanAhsoka Tano.[3]
